Atheist Rap Music?

I do believe that my first foray into reallly exploring Atheism while being Black (and convinced that it was okay be both, that I wasn't alone) was when I found Atheist rap music, namely two Black rappers that were open with their atheism. There is Greydon Square, ,who has a song callled Black Atheist, and other songs and then some time later I found Tombstone da Deadman. I was wondering what people's thoughts were on this genre of music? Does any one have any other artists to share?
